July: James E. Holmes dressed head-to-toe in protective tactical gear, set off two devices of some kind before spraying the Century 16 theater with bullets from an AR-15 rifle, a 12-gauge shotgun and at least one of two .40-caliber handguns in Aurora, Co. during the screening of the new Batman film. Twelve people were killed in the rampage and over 50 were injured. (Photo: AP)
